Panel Assembly Structure

1. A panel assembly structure suitable for assembling a panel on an inner surface of a panel cover, the panel assembly structure comprising: a first connecting portion, integrally formed on the inner surface of the panel cover and extending toward a first side of the panel and having a first connecting through hole; a first screw, screwed into the first connecting through hole and a first panel threaded hole of the first side of the panel for fastening the first connecting portion and the first side of the panel together; a second connecting portion, integrally formed on the inner surface of the panel cover and extending toward a second side corresponding to the first side of the panel and having a second connecting through hole; a second screw, screwed into the second connecting through hole and a second panel threaded hole of the second side of the panel for fastening the second connecting portion and the second side of the panel together; and an elastic washer, placed between the first connecting portion and the first side of the panel and having a washer through hole, wherein the first screw is sequentially screwed into the first connecting through hole, the washer through hole, and the first panel threaded hole, and two ends of the elastic washer have a first engaged portion, respectively, and both sides of the first connecting portion have a second engaged portion, respectively, for being clipped to the corresponding first engaged portion, so as to restrict the position of the elastic washer relative to the first connecting portion.

2. The panel assembly structure as claimed in claim 1 , wherein the elastic washer has a sleeve having the washer through hole.

3. The panel assembly structure as claimed in claim 2 , further comprising: a buffer member, having a buffer through hole, wherein the buffer member is disposed on the outer edge of the sleeve through the buffer through hole and is placed between the elastic washer and the first connecting portion.

4. The panel assembly structure as claimed in claim 3 , wherein the buffer member is a spring or a rubber.

5. The panel assembly structure as claimed in claim 1 , further comprising: a buffer member, placed between the first side of the panel and the first connecting portion.

6. The panel assembly structure as claimed in claim 5 , wherein the buffer member has a buffer through hole, and the first screw is screwed into the first panel threaded hole through the first connecting through hole and the buffer through hole.

7. The panel assembly structure as claimed in claim 6 , wherein the buffer member is a spring or a rubber.

8. A panel assembly structure suitable for assembling a panel to a panel cover, the panel assembly structure comprising: a pair of screws respectively disposed on two corresponding sides of the panel cover, for fixing the panel placed between the two corresponding sides of the panel cover on the panel cover; and an elastic washer placed between a head of one of the pair of screws and one side of the panel corresponding to the screw, wherein two ends of the elastic washer have a first engaged portion, respectively, the side of the panel cover where the elastic washer is placed has a connecting portion, and both sides of the connecting portion respectively have a second engaged portion suitable for being clipped to the corresponding first engaged portion, so as to restrict the position of the elastic washer relative to the connecting portion.

9. The panel assembly structure as claimed in claim 8 , wherein the elastic washer has a sleeve having a washer through hole, and the screw is screwed into the washer through hole.

10. The panel assembly structure as claimed in claim 9 , further comprising: a buffer member, having a buffer through hole, wherein the buffer member is disposed on the outer edge of the sleeve through the buffer through hole and is placed between the elastic washer and the connecting portion.

11. The panel assembly structure as claimed in claim 10 , wherein the buffer member is a spring or a rubber.

12. The panel assembly structure as claimed in claim 8 , further comprising: a buffer member, placed between the first side of the panel and the connecting portion.

13. The panel assembly structure as claimed in claim 12 , wherein the connecting portion has a connecting through hole, the buffer member has a buffer through hole, the corresponding side of the panel has a panel threaded hole, and the first screw is screwed into the panel threaded hole through the connecting through hole and the buffer member through hole.

14. The panel assembly structure as claimed in claim 13 , wherein the buffer member is a spring or a rubber.
